CATTLE-GUARD.

Specification of Letters Patent. Application filed February 14, 1912. Serial No.

Patented Dec. 10, 1912. 677,478.

To all whom it may concern:

Be it "known that I, FnRsoN WAILACE LULL, a citizen of the United States, residingat Oso, in the county of Snohomish and.

,5 State ofWashingtom'have invented certain new and useful Improvements in Cattle- Guards, of which the following is a specification reference being had to the accompanying drawings. y i

y invention relates to new and useful improvements in cattle guards, and the primary object of the invention is to provide a device of this character which will be most I efiicient in preventing cattle from walking between the rails, and thereby eliminate "the danger of having thesame killed by passing trains.

A further object of the invention resides in providing platforms between and on the sides of the tracks which with swinging gates to swing the latter horizontally across the tracks when weight is placed on said platforms.

A still further object of the invention resides in providing a device which is simple and durable in constructiominexpensive to' manufacture-and one which will be very ellicient and useful in operation.

In the accompanying drawings forming a Figure 1 is a top plan view showing my device applied to use; Fig. 2 is a longitudinal section through the device as seen on the line 2 2 of Fig. 1; and Fig. 3- is a transverse section therethrough, asseen on the line 3 -3 of Fig. 1, showing the gates in closed position. l

11 carrying out my invention, I shall refer to the drawings, in which similar reference characters designate corresponding pahrlzts throughout the several views, and in w 0 1 1 indicates rails mounted in the usual or any preferred manner upon the ties.

2 and 3 indicate a'road crossingover the railsl, n

A fence 4 extendin on both sides of the track for a considera le length thereof, is provided to prevent the cattle and other animals on adjacent farms from crossing the said track and in order to further prevent these animals from walking on the track after passing over the crossing 3, I

" rovide my mproved guard which will he hereinafter and more particularly described as in d tail.

tal

contact with the limit the outwar have connection uate arms ..or stems 15 are Ge sin of the lies 2 are of greater length these ties of lncrea'sed lengthare mounted vertical, posts 5 on each side of the track, said posts supporting thereon the horizonlyswinging gates 6. The upper portions of these gates are provided with arms or the like 7 which are disposed in alinement with said gates proper and also mounted on the tie upon WhlCh the posts 5 are mounted,

are the additional posts 8 which are disposed beyond the posts 5 and are adapted to swung in their horizontal position across the track, while an additional tie of increased width is provided with the stopping posts19 disposed in substantial alinement with the posts 5, which stopping posts are adapted to swinging movement of said gates. 5

A rock shaft 10 having crank portions 11 thereon suitably journaled in. bearings 12 on the lower face ofthe track rails '1, has the outer ends thereof, bent to form crank arms 12, each of which arms has mounted thereon'a weight 13. The-free ends of the crank arms 12 have in linking engagement therewith the connectin arms 14 which have the opposite ends of the same engaged with arcuate stems'or arms 15 carried on the lower portions of the gates 6. These arcdis osed inom this wardly toward therails 1 and construction it will be seen that through the mediiim of the weights, said rock shaft 10 will be normally disposed in such a position as will dispose the gates 6 in their 0 en positions,'as shown in Fig 1. roc shaft than ordinarily are provided and on one of arms 7, as said gates are 4 10 is disposed immediately forward of the tie having the gate posts mounted thereon, and mounted on the tie in the rear of this last'mentioned tie are a pluralityof transverse bars 16 which are disposed between said rails and on each side of the same, at t e same time being spaced slightly above said tie. Pivotall mounted on these transversely disposed [in 17, each of which is provided with a air of arms 18 and these arms are inclined s ig'htly downward to project-under the rock shaft 10. These platforms are pivoted at one end thereof on the bars 16 whilethe opposite aredisposed toward free ends of the same and adjacent to the crossing 3 and as a weight is placed on any of said latforms, the shaft 10 will be caused to reel? whereby the gates 6 will be swung horizontally across rs 16 are the platform carrying my invention into practice with- "ciibiu of this patent may :ohtainefi for the track to obstruct the passage way thereon. As soon as the weight has been remove from the platforms, however, the gates will be returned to their initial positions through the medium of the weights 13, and in order u s thereof, the guards or the like 18 are mounted on to guard the platforms from the side the adjacent ties.

in the drawing and, spec fication,

shown and descrihecl a single cattle guard.

disposed on the one side of thecrossing 3,- hut it will, of course, be understood that a similar guard is used. in connection with the rails on the opposite side of said crossing (not shown). In view of the fact that the fence 3 extends along the line of rails, the animals will find that 'the only means for entering the space between the-rails will be from the crossing i3,but it willbe seen that as soon as a weight is placed on any platforms 17 the proper gate will be closed to obstruct the path, An animal finding the path along the track obstructed by the gates,

will return to his proper pasture and thus be saved from a possible death by being struck by the passing train.

From. the foregoing, it will be seen that I have provided a simple, inexpensive and e licient -means for carrying out the of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in therform, proportions in the minor details of construction may, be resorted to for successfully out departing from the spirit or sacrificing of the principles thereof.

Having thus described my invention, what I claim is z- In a dattle ;the combination with a pair of rails and t es therefor, certain of I have sitions of the objects five cents each, by addressing the Washington, D. 0.
